First the odd public embarrassment... Matt did an awesome job with this module! Both the hardware and drivers are very very nice. Edit: I will add videos as I make more, to avoid spamming the forum with random little videos subscribe on youtube to catch them all! Code -  ComboLock.zip   119.74KB   16 downloads Code - http://sdrv.ms/MUeRa3 Let me know if i can clear something up, I'd be happy to help.

I finally got around to making something with my mini that has a somewhat permanent use. Check out the video first to see its beauty



Some notes:
The RGB LED strip is common anode, so if your strip is common cathode make sure you change the wiring to account for that. The code as well, because the lights are on when the signal is LOW the lights in code are on when they duty cycle is 0. If your lights are common cathode you'll have to keep that in mind.

The chips I used are the MAXIM MAX4420, they are High-Speed 6A single MOSFET drivers. Note they 'single', you'll need one per color or for each section you want to control individually.

Pretty picture time!

I promise I am not a zombie, I've been alive all along! Older members here might already know me, but for the new people (many of which I have yet to 'meet'): I am Omar, a curious teenage programmer, and I am back to making netduino videos! Hopefully on a regular basis again Here it is, the first of many to come:

This is a touch screen keyboard with most keys found on a regular keyboard. It is a USB touch screen keyboard powered by 4DGL code, .netmf USB HID code (uses my USB HID Keyboard class). This runs on the 32PT touch screen from 4D Systems, and a netduino. You can use the keyboard class without the screen.  Netduino Touch Keyboard.zip   165.82KB   211 downloads Here is the screen's code:  screen 4DGL code.txt   8.84KB   69 downloads Let me know if you find bugs.

Here is a quick video of it in action.



This will make the netduino a USB HID, so the netduino will simulate a keyboard in this case.
To get your netduino ready for this:
1 Install firmware 4.1.1 http://forums.netdui...re-v411-beta-1/
2. Transfer to Serial deployment http://forums.netdui...b-and-com1com2/
3. Create a project and put the class in it, add the test code to your program's main method
4. Hook up a usb to serial like this: http://www.sparkfun.com/products/9873 to your netduino's com1 or 2, which ever you chose while setting serial deployment
5. Change deployment in VS to Serial, select your com port
6. Power your netduino with a 9V battery or whatever, except usb. Deploy.
7. You need the code to run and set up the usb stream first, then connect your usb cable.

Sample use. As in the video.

            string setupResult = Keyboard.SetUp();

            Debug.Print(setupResult);

            if (setupResult != "Success")
                return;

            while (true)
            {
                led.Write(true);
                if (button.Read())
                    Keyboard.SendString("/*\n" +
         "* Supported Characters (with this method):\n" +
         "* abcdefghijklmnopqrstuvwxyz\n" +
         "* ABCDEFGHIJKLMNOPQRSTUVWXYZ\n" +
         "* 0123456789\n" +
         "* enter escape backspace deletethis\b\b\b\b\b\b\b\b\b\b \ttab   space\n" +
         "* - = [ { ] } \\ | , > . < / ? ! @ # $ % ^ & * ( )\n" +
         "*/");
                led.Write(false);
                Thread.Sleep(2000);
            }

Projects using the netduino as a keyboard coming sometime soon. I want to make a mouse class next.

I found this:

in the original code from the USB HID example. I added that I expanded it. I am not big on licenses, but I think I must add it to my code as well. License info here: http://www.apache.or...ICENSE-2.0.html
